Abstract: A loudspeaker comprises a reflex port located within the enclosure at a point substantially co-incident with a nodal surface of at least one resonant mode within the enclosure. The amplitude of that resonance at the input to the duct is minimised, hence assisting in filtering out the effect of that resonance without needing absorptive material. Ideally, it is placed at the intersection of two or more nodal surfaces.

Abstract: A technique that identifies registered or guest users in web meetings of the type wherein users must follow a supplied URL to attend the meeting. Registered and guest users are provided different forms of the meeting invite URL. Each registered user receives a common web meeting link (a URL) that he must follow to join the meeting. This link forces the registered user to authenticate to the service when used. A guest user invitee receives a unique URL for the meeting that is generated with a nonce value associated with the guess user's contact information. The nonce value does not expose the contact information. To join the meeting, each registered user must follow the common web meeting link and authenticate to the service. True identities of the web meeting participants are displayed.

Abstract: Approaches for analyzing a power grid of an integrated circuit are described. In one embodiment, a method includes selecting at least one portion of the integrated circuit to be analyzed. A power grid model corresponding to the integrated circuit is retrieved from a database, and a first simulation of the programmable integrated circuit is performed. The first simulation generates a respective waveform of an electrical characteristic over time for each connection of a component within the selected portion to voltage supply or voltage ground. A simulation is performed of the power grid model using the respective waveforms as input stimulus for each connection in the selected portion.

Abstract: A multi-leaf collimator for a radiotherapy apparatus comprises a plurality of elongate leaves mounted in a carriage, the carriage being mounted on a substrate, wherein the leaves are independently moveable relative to the carriage in a longitudinal direction, and the carriage is moveable in that direction relative to the substrate, and a control apparatus is arranged to receive a signal representing leaf positions relative to the substrate and to control the leaf positions relative to the carriage and the carriage positions relative to the substrate so as to achieve those leaf positions relative to the substrate. Most MLCs sense the current positions of the leaves relative to the substrate. The control apparatus can therefore compare the current leaf positions to the signaled leaf positions, and move the leaves and the carriage accordingly. A corresponding method is also disclosed.

Abstract: An amplifier may include two or more pulse-width modulators controlling respective sets of switches to produce an amplified version of a source signal. A positive DC-offset based on the source signal may be applied to the pulse-width modulator controlling one respective set of switches, and an equal value negative DC-offset may be applied to the pulse-width modulator controlling the other respective set of switches, to provide an effective offset between the respective points in time of the rising/falling edges of the different pulse-width modulated control signals. The addition of alternating positive and negative DC-offset values doesn't affect the output load, and doesn't degrade the signal. The DC-offsets may be added at a frequency selected to be beyond the signal baseband, and the value of the small input signal level may be determined using an RMS level comparator or similar measurement technique.

Abstract: An amplifier may include two or more pulse-width modulators (PWMs) controlling respective sets of switches to produce an amplified version of a source signal. The clocking for the amplifier may be controlled to delay signal processing within the PWMs relative to one another in time, thereby providing an effective time offset between the respective edge transitions of the controlling signals provided to the respective sets of switches. The PWMs may count down to zero from the next PWM duty-cycle value when a new data sample is detected, beginning a new count for each new sample, with the PWM outputting a pulse when the counter value is nonzero. A “data-sample-ready” signal may be decoded from a master counter, which may be clocked based on the high speed PWM clock, and the decode value may be adjusted to determine when the PWM should initialize to the next data sample.

Abstract: Predicting simultaneous switching output noise of an IC device is described. User input is obtained. The user input includes: an identification of an input/output bank of an integrated circuit die; an identification of a device package substrate to which the integrated circuit die is to be attached; and an identification of input/output interface to be used by the input/output bank. A noise factor and an impedance are selected responsive to the user input. The noise factor is multiplied with the impedance to provide a result. The result, which is output, is a prediction of the simultaneous switching output noise of the integrated circuit device.

Abstract: A loudspeaker radiating diaphragm can be stiffened to help increase the breakup frequency to above the working frequency range of the driver concerned, by forming it of a moulded part and an attached formed part. The moulded part is a radiating surface with stiffening ribs. The formed part is a thin surface of high modulus material, attached to the rear of the ribs. The overall structure can have significantly higher stiffness than either of the two parts. This helps in designing a loudspeaker driver that does not breakup within its working frequency range.

Abstract: A user authenticates to a Web- or cloud-based application from a browser-based client. The browser-based client has an associated rich client. After a session is initiated from the browser-based client (and a credential obtained), the user can discover that the rich client is available and cause it to obtain the credential (or a new one) for use in authenticating the user to the application (using the rich client) automatically, i.e., without additional user input. An application interface provides the user with a display by which the user can configure the rich client authentication operation, such as specifying whether the rich client should be authenticated automatically if it detected as running, whether and what extent access to the application by the rich client is to be restricted, if and when access to the application by the rich client is to be revoked, and the like.

Abstract: The relative timing of triggering switching events in a circuit block of an IC device is dynamically adjusted in response to fluctuations in device's supply voltage to minimize clock jitter caused by supply voltage noise. A control circuit monitors supply voltage fluctuations, and in response thereto dynamically phase-shifts a clock signal that triggers the switching events so that the switching events occur during relatively quiet time intervals in which fluctuations in the supply voltage are minimal.

Abstract: Systems and methods for selecting a mask system for a patient are provided. Certain example embodiments include generating 3D contours of patients and selecting mask systems based at least on these contours. These contours may be generated by using, for example, a cushion of translatable pins, a nasal cannular scanning device, and/or a shadow stereopsis sensor. Certain other example embodiments allow images and/or videos to be captured and optionally synchronized. Then, images of various mask systems may be overlaid to determine how well a mask system fits. In still other embodiments, a user can hold a transparency corresponding to a mask design in front of the patient's face to determine how well a mask system fits.

Abstract: A rich client performs single sign-on (SSO) to access a web- or cloud-based application. According to the described SSO approach, the rich client delegates to its native application server the task of obtaining a credential, such as a SAML assertion. The native server, acting on behalf of the user, obtains an assertion from a federated identity provider (IdP) that is then returned to the rich client. The rich client provides the assertion to a cloud-based proxy, which presents the assertion to an identity manager to attempt to prove that the user is entitled to access the web- or cloud-based application using the rich client. If the assertion can be verified, it is exchanged with a signed token, such as a token designed to protect against cross-site request forgery (CSRF). The rich client then accesses the web- or cloud-based application making a REST call that includes the signed token. The application, which recognizes the request as trustworthy, responds to the call with the requested data.
